Imaginative World Modeling With Scene Graphs via VLM for Object Navigation

Semantic navigation requires an agent to navigate toward a specified target in an unseen environment. Employing an imaginative navigation strategy that predicts future scenes before taking action, can empower the agent to find target faster. Inspired by this idea, we propose SGImagineNav, a novel imaginative navigation...

GINIO: A Geometric SO(3)-Equivariant Interface for Neural Inertial Odometry

Neural inertial odometry increasingly uses networks as learned measurements inside filtering pipelines. Such measurements should transform consistently under arbitrary IMU mounting conventions: their mean must transform as a vector, and their covariance must transform congruently as a second-order tensor. We present GI...

NavVerse: Benchmarking Indoor-to-Outdoor Embodied Navigation in Continuous Robot Simulation

NavVerse is introduced, a physics-enabled benchmark for indoor-to-outdoor embodied navigation, and zero-shot experiments with RL, VLA, and modular baselines show that current agents remain far from solving cross-context navigation.

A Replay-Constrained Simulation Framework for Personalization of Powered Knee-Ankle Prosthesis Controllers

A replay-constrained simulation framework that supports scalable high-dimensional personalization of powered prosthetic legs and is amenable to extension to higher-dimensional controller parameterizations such as neural-network controllers is presented.

Cyclops: LiDAR as a Camera That Dreams in Color

Cyclops is proposed, a framework that translates sparse Non-Repetitive Scanning LiDAR intensity into RGB video, enabling camera-free inference for all-day perception tasks and mitigating inter-frame flickering.
